It was only a matter of time before the three unlockable characters for Mario Kart Arcade GP DX were revealed. As seen in the image above, Bowser Jr. is the first unlockable character, leaving two more slots open for debate and speculation. We already know that both Rosalina and Metal Mario have their own unlockable karts in the game, but Wario and Waluigi emblems have been spotted on the sides of the arcade machine. It won’t be long before players discover the last two characters!
